I'm considering on getting a 4 week tesol certificate (with a teaching practicum) with Midwest Education group to teach in Kuwait. I've taught in South Korea for 2 years and I'm interested in teaching in the Middle East.

What does anyone know about this group?
Are they reputable? (I am well aware that the best known TESOL is a CELTA and the benefits of a CELTA - this just came up)
Is their TESOL certificate worth anything or is it a scam?
